In this chapter, we learn that Miyu and the other students are busy preparing for the upcoming holiday season. Miyu is working on a new costume for her, and Miyu wants to make sure that she's wearing something that's appropriate for the season. She tells Miyu that her last costume was a total disaster, and she wants something more appropriate for this year. She's thinking of a costume for a cat, since she'd like to wear a kimono and ears and tails. She also wants to wear some fangs, since that'll make her look like a cat. Miy thinks it's cool, but Miyu doesn't want to wear it, since it'll ruin her stretching atmo . So Miyu suggests that they go check out some of the decorations in the storeroom, since they've been using them for the last few years. She asks Miyu to stand aside while she goes to get the decorations, since her butt is bothering her.
